What is the difference between Full-penetration butt welds and filet butt weld?
tell me full penetration joint process
How do you measure penetration in welding?
To measure penetration of a weld, one must cut and etch the weld, preferably on a test coupon. Etching is just using an acid that will discolor the weld metal so that there is a visible difference between the weld metal and the base metal. Once the acid has taken affect, one can measure the weld using calipers or a similar measuring device.
What is a weld backgouge?
A Backgouge consists of preparation of the second side of full penetration welds to the extent necessary to permit the proper deposition of weld metal.
How do you test partial penetration welds?
Partial Penetration Weldments could be tested using Ultrasound Testing method. It should not be used to evaluate the intergrity of the weld but could be used to detect the root penetration and the depth. Godfrey Tisseverasinghe
What does the term lack of penetration mean in welding?
Incomplete penetration (IP) or lack of penetration (LOP)occurs when the weld metal fails to penetrate the joint. It is one of the most objectionable weld discontinuities. Lack of penetration allows a natural stress riser from which a crack may propagate. The appearance on a radiograph is a dark area with well-defined, straight edges that follows the land or root face down the center of the weldment.Mechanical Design EngineerMoustafa I.

Difference between Full Penetration weld Deep Penetration weld?
The difference between a full penetration weld and a deep penetration weld is the depth at which the metals being joined are actually joined. A full penetration weld is a slight puncture only to heat the two metals and join them. A deep penetration weld is a deeper hole puncture that is held and a metal wire is melted to join the metals.
What does FP on a weld symbol mean?
Full penetration.
If the weld does not combine with another weld or the base metal it is referred to as?
Lack of fusion and inadequate penetration.
Is a flare groove weld considered a partial penetration weld?
Without knowing exactly which Code or industry this applies to, I'll give it a shot using AWS D1.1 standards. The standard flare-groove detail is P10 indicating that it is a PJP (partial joint penetration) weld. If a weld size is not indicated, it is assumed it is a full thickness weld and I believe this is where the confusion comes in. It's a partial penetration with full thickness and that's where the argument starts. This weld could be used as a full penetration weld (and held to that testing criteria) but the detailer must be specific about the intentions, particularly if it is used in a critical joint.

What is a penetration weld?
a weld that does exactly what it sounds like, the molten metal that is created when welding is created all the way through the materials being welded. for example, if it is a 1/16th inch steel plate, a full penetration weld would create a molten bead from the front to the back of the plate. A full pin weld is when u have a bevel on one side that u weld first flip it over arc air gouge the other side and weld that side up
What is the effect on the weld if the electrode is held to closely to material being weld?
it will lead to increased amperage and decreased volts. more penetration and a faster deposition rate

What does CJP Bot Weld type means?
cjp =complete joint penetration typ =typical
What electrodes would you select to produce a weld with shallow penetration E6010 or E6011 or E6013 or E7018?
